CLINTON 0. MIKLE, OF PORTLAND, OREGON.

AUTOMATIC SASH-STOP.

Application filed December 15, 1915.

To all whom it may concern Be it known that I, CLINTON O. MIKLE, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Improvement in Automatic Sash- Stops, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to that class of device used particularly for double sashes in windows and especially for railroad coach windows.

The object of my invention is to provide a sash stop on the outer sash to hold the inside sash by automatic action and at the same time allow of both sashes being raised or lowered by manipulation of my device. I attain these objects, as well as other advantages, by the construction, combination and arrangement of parts illustrated in the accompanying drawings, which form a part hereof.

Figure 1 is a front elevation of my device showing position of spindle when the stop or catch is in horizontal position. Fig. 2 IS a sectional view of the same device on the line 22 of Fig. 1. Fig. 3 is a side sectional elevation of a window frame, partly broken away, with outer and inner sashes and the device secured to the outer sash in operative position. Fig. 4 is a plan View of the device shown in Fig. 1.

Like letters and numerals refer to like parts throughout the views.

A is the casing of the device.

B is a stop or catch.

C is the catch operating spindle.

D is a horizontal pivot in the casing and on which the catch B is mounted.

E is a horizontal pivot of the spindle C, the ends of which are mounted in ears 00 on the lower side of the catch B. When down the catch engages the upper edge 5 of the casing A and extends over the casmg a suitable distance, and sufliciently to engage the lower edge of the inner sash when it is above the stop or catch.

In Fig. 3 is shown a window frame 6, partly broken away, an outer sash 7 and an inner sash 8 each in vertical section. My device is shown in this figure secured to the stile 9 of the sash 7 and the catch B in engagement with the lower edge of the stile Specification of Letters Patent.

10 of the sash 8. The window sill 11 also appears in this figure.

It is now apparent that when the outer sash 7 is down, the lower end of the spindle C will be in engagement with the sill 11. When the sash is lowered to this position the spindle C is caused to move upward and in turn to move the catch B upward to the position of same shown by the dotted lines in Fig. 3. When in this position the inner sash 8 can be raised or lowered and pass the catch B without engaging it.

It will be further apparent that when the inner sash 8 is raised a sufficient height to allow access to the outer sash 7, the latter, upon being raised, causes the spindle C and catch B to fall by gravity action to the position shown in the views. It is then obvious that the outer sash cannot be raised beyond the height where the catch engages the lower edge of the sash 8. To raise it farther, it is necessary to lower it sufliciently to allow the spindle C to be moved upward by pressure of the hand on its lower end, which raises the catch and permits the outer sash to be raised to the desired height. Upon releasing the spindle the catch falls against the inner sash and when the outer one is lowered the catch slides along the former until it passes below it.

It is known that persons operating double sashes in railroad coaches are often injured by catching their'fingers between the two sashes when attempting to raise the outer one. I have sought to prevent this by the use of my device. It will be seen that a person trying to raise an outer sash provided with my device is prevented from doing this beyond the distance where the stop engages the inner sash. Upon realizing this obstruction a careless person is then compelled to put one hand under the outer sash to press the spindle upward and retain it there, and will naturally place the other hand also under the sash. This brings the hands into safe positions and avoids injuries. The same thing would obtain if the operator raises the outer sash in the first place sufliciently to get the hands under so it will move upward continuously. In any event the operation of the catch is automatic and at the same time it can be manipulated so as to allow the free movement of both sashes as desired.

I contend that I have thus provided a device for' the purpose intended, and of a simple, practical and cheap form, also that the object thereof is fully accomplished, as demonstrated herein.

Having thus fully described my inven- 7 tion I claim:

1. An automatic sash stop or catch of the character described, comprising a vertical casing, a stop or catch pivoted in the upper end of the casing, extending over the casing a suitable distance andengaging its upper end When the stop is in a horizontal position, a spindle Within the casing vertically movable therein, its upperend pivoted in the lower part of thesaid stop, the spindle being of suflicient'length to extend a suitable distance below the lower end of the casing v When the stop is in a horizontal position,

substantially as described.

2.1 An' automatic sash stop of the characspindle Within the casing vertically movable therein, its upper end pivoted in the lower part of the said stop, the spindle being of sufiicient length to extend a suitable distance below the loWer end of the casing When the stop is in a horizontal position, substantially as described.
